Title: 3-piece Crank Spindle ID - Profile or something else?
Post by: Mikku on September 13, 2021, 11:42 AM
Am trying to ID a 19mm, 48-spline spindle which came with some used, 182mm Profile cranks. I don't know its age but it's solid, measures just under 14cm, so is about 5 1/2? in old money. There may possibly be some stamping on it but it's not clear enough for me to be sure if it is a stamp or just a mark. The 3rd pic is the best pic I could take of whatever it is. ::)

I don't know much about three-piece cranks but am not sure that Profile made spindles in this length, in which case does anyone have an idea what other brand it might be? Thanks in advance. :daumenhoch:

Its almost impossible to know. I guess you could weigh it, then look up what a Profile axle is supposed to weigh?

For many years other companies have been making them. I've bought a few, and been given a couple also. The one I have right now is Profile as it came with my Maderas, but no stamp or anything else.

BTW take the bolt out and get me a shot of the end. Mine has markings on it, look like a clock. Around the bolt hole in the end like.

Thanks mate! Below's a pic of the spindle end, as well as the bolt itself.

Being 5 and a half inches, it's not much smaller than the standard Profile ones, so hopefully wouldn't cause much of a problem. :daumenhoch:

Yeah that looks like a Profile to me. I know they do them longer also. Especially when you use super long arms like you have. It needs more spacing, or it hits the frame at the pedal end dude.
